Importers of Cyclanic, Cyclenic & Cycloterpenic Ketones Without Other Oxygen Function (NESOI) paid $2.7M in duties in August 2026, an average duty rate of 15.78% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule. Cyclanic, Cyclenic & Cycloterpenic Ketones Without Other Oxygen Function (NESOI) imports of $16.8M in August 2026 ran 24% above the year-to-date monthly average of $13.5M.
Last updated: August 2026 dataThis residual heading for cyclic ketones without additional oxygen functions spans commercially distinct compounds including isophorone (2914291000), natural camphor (2914293000), synthetic camphor (2914293100), camphor (2-camphanone) (2914293200), and other cyclic ketones (2914295000 and 2914299000). India leads US imports across this heading, reflecting its significant camphor and isophorone production capacity. Isophorone is a high-value solvent for coatings and a building block for isophorone diisocyanate (IPDI), while camphor has pharmaceutical, cosmetic, and industrial uses — making the specific tariff line selection critical for accurate duty and trade-remedy assessment.

The US tariff schedule enumerates them separately: natural camphor at 2914293000 and synthetic camphor at 2914293100, with camphor (2-camphanone) at 2914293200. Natural camphor is derived from Cinnamomum camphora trees, while synthetic camphor is produced from turpentine-derived pinene. A certificate of origin and production method documentation may be required to support the correct line.
Isophorone (2914291000) is primarily consumed as a high-boiling solvent in industrial coatings, printing inks, and leather finishes, and as a chemical intermediate for isophorone diisocyanate (IPDI) used in polyurethane production. Its relatively low volatility and strong solvency make it preferred in applications where slower evaporation is needed.
